Although tea is the world's most widely consumed beverage Do these data suggest that true average folacin content after water, little is known about its nutritional value. Folacin is the same for all brands? (yes or No) p value (0.xxx) is the only B vitamin present in any significant amount in tea, Are the variances close enough to be considered the same? (Yes or No) 1000 0 and recent advances in assay methods have made accurate Minimum difference to be be considered different (1 decimal) determination of folacin content feasible. Consider the Number of significant differences accompanying data on folacin content for randomly selected specimens of the four leading brands of green tea. (Data is based on "Folacin Content of Tea," J. of the Amer. Dietetic Assoc., 1983: 627-632.) Does this data suggest that Show your work true average folacin content is the same for all brands? a. Carry out a test using a = .05 via the P-value method. b. Assess the plausibility of any assumptions required for your analysis in part (a). c. Perform a multiple comparisons analysis to identify sig- nificant differences among brands. 7.2 10 10.1 7.3 7.5 9.6 7.3 9.9 7.7 6.9 9.4 AW NH 8.3 6.2 8.1 5.8 6 .5 6.7 6.5 7.9 2.4 5.3 6.5 5.6
